Applicant's summary and conclusion
- Interpretation of results:
- Category 4 based on GHS criteria
- Conclusions:
- The acute oral LD50 value was considered to be 800 mg/kg bw, when 10 rats were treated with the given test chemical via oral route.
- Executive summary:
Acute oral toxicity study of the given test chemical was conducted in 10 rats at the dose concentration range of 100-1600 mg/kg bw. The given test chemical (undiluted) was administered via oral route.Animals were observed for mortality, body weight change and clinical signs for 14 days.
Mortality was observed within 2 hrs to 1 day in treated animals at 800 mg/kg bw. Symptoms included weakness, roughening of the coat, cyanosis, tremors, darkening of the eyes, and lacrimation just before death. Body weight change was observed in more than 6 animals.
Under the condition of this, the LD50 value was considered to be 800 mg/kg bw, when 10 rats were treated with the given test chemical via oral route.
